-- My invention is'an improvement in tools for special work, and relates more especially;

to a tool for use in widening thecra'cks in plastered walls so that, they can be more 6" easily filled in pointing up. I

V The principal object of myinve'ntion'is to provide a handledtool or implement for use by plasterers, painters, paper-hangers, and

other workmen which will greatly facilitate the operation of preparingcracks and other defects in plastered walls,'in the present ni tance providing a cutting implement o scraperin the form of a claw with a tens on.

device for regulating the depth to which the scraper will enter the crack and IIl WllICl'I I theshape of saidcutting implement 1s such that it will bevel the :edges'of the crack to. better "receive the plaster-or filling material used in pointing up the wall" for'finishing the surface thereofby painting orpapering' J A further object of my invention is topro-f .videan implement of this'cha'racter withra'" wedge-shaped scraper or blunt chisel at the otherend ofthehandle fromthecutting tool which-can be used in cutting'out plasterin" corners or other places where thecutting tool in the form of a claw'cannot lie-conveniently;

tachment thereto. thespring device and shank of the clawreference indicate like parts the-different figures of the'drawings'. in carrying out'myinventionone part of the tool orimplement is in the form of a claw 1 10 having-ashank 11 bywhichit is connected to; a handle 12passing through the center 56 thereof-andprojecting vbeyond the rear end where said shank is reduced in diameter .to providea threadedtang 13for securing the wedge-shaped scraper or blunt chisel 14: to

theend of thehandle opposite the claw, the 60. forwardend of the handle from which the claw projects having a ferrule l5. As will be noted by reference to the drawings the claw projects at an angle" from, the shank and is substantially diamond-shaped at its lower 66. end with an angular or V-shaped point 16 at thefcenterof the innerside of said claw, this part of the tool or implement beingused for the purpose of scratching or beveling the edges of a crack to receive material as plaster in pointing up or closing the crack.

I i-order to keep the claw-shaped scraper uprightand limittheextent to which it enters the crack in the wall to be enlarged for. pointing; up I provide a roller 17 carried by a ten- '75 sion device and located at the outer side of thegend of thef scraper, said tension device consisting Lolarms 18, 18 securedto the handle and diverging ,therefrom with. the roller-rotatably mounted on the crosspiece19 connecting said arms, the latter being under spring tension forwhich purpose the support- 7 ing device for the roller is formedof spring wire witha coil 20 at the inner end of each arm'beyond which the terminal portions 21 85, of the'wire f extend into the handle for at- To intimately connect shaped cutter'to the-handle the underside of the shank is cut awayor recessed at 22 to re Q 'ceive the terminal portions 23 of the wire forming the tension device for supporting the roller, said recess being of the same length asfsaid' t'erminaliportions toinsure binding en a ement-withthe handle when the wedge- 95,
